Fit Conditions
Cearvol Wave Initial and Tuned Results
We tested the Cearvol Wave in both its out-of-box Initial configuration and after professional Tuned adjustments. Select either fit condition below to see how settings affected measured performance.
Out of the box with power dome coupling, the Cearvol Wave delivers strong performance with a normalized Initial Score of 4.3/5. Speech in quiet measures 4.0/5, well above the category average, while speech in noise reaches 2.4/5. Music streaming is a highlight at 4.1/5. Feedback handling is solid at 3.8/5, and own-voice comfort scores 2.1/5. The integrated receiver design requires no separate component selection, making initial setup straightforward for users.
What is HearAdvisor's Initial Fit?
The Initial Fit approximates the most likely settings and eartips for a typical moderate hearing loss. Results are measured across the same 72 acoustic scenes in our custom-built lab, then scored on a 5-star scale using an auditory model.
